1818 Market Street

1818 Market Street is a 40-story office tower in the International Style featuring clean lines, functional design, and a prominent glass and steel facade. The building offers open, bright work floors with generous window openings on each level.

The tower was designed by EwingCole and completed in 1974 during a construction boom for high-rise offices in Philadelphia. This period marked a significant modernization of the city's business district.

The building shaped Philadelphia's commercial image during its emergence as a major business hub and continues to define the downtown skyline. It reflects the architectural choices that made the city's center feel modern and corporate.

The building sits near public transportation connections and is easily walkable from Philadelphia's downtown core. Keep in mind this is an active office building with limited public access to interior spaces.

The building employs floor-to-ceiling glazing that brings maximum natural light into every office area, a design approach that was significant for workplace quality in the 1970s. This focus on daylight penetration helped define better working conditions for the time.
